Startrek at home.
This movie started a very series, one that I did enjoy at the time. Any world could be visited and hence any subject could be explored. The actual movie wasn't brilliant, good but not brilliant, it didn't quite feel like a big budget movie, the special effects weren't over the top. if you a sci-fi fan you should watch the movie and will probably enjoy and then get into the TV series.
The good Dr. soon learns that the artefact found back in 1928 was developed by an ancient and advanced alien race., they used it to teleport between worlds. The military see the device as a threat, as the alien race could come back through the stargate, invade and conquer Earth.
Hence a mission is set up to travel to the other stargate on the other world and destroy it. While on the alien planet the team find resembles ancient Egypt and is ruled by the sun god Ra. The inhabitants of the planet are slaves with all education, science and technology kept from them. Only Ra and his family can use their technology.
So now the question is do the team help start an uprising and free the people of the planet?
